Abstract (en)
[origin: WO2021012058A1] A distal entry point (DEP) to brain aspiration (D2BA) catheter for use in an endovascular procedure for gaining access to cervical and cerebral arteries in a brain of a patient and aspirating one or more intracranial clots from the cerebral arteries, comprising a soft distal tip region having a distal length sufficient to extend from a level 1 or level 2 arterial segment of a cerebral artery or equivalent to an upper neck arterial vessel, a stiffness enabling movement through the level 1 or level 2 arterial segment of the cerebral artery, and an outside diameter (OD) of 6F-10F, a proximal region having a stiffness greater than the stiffness of the soft distal tip region, the proximal region having a length sufficient to extend to outside the patient through the DEP.
